I've seen the Nitecore i2 2016 version on Amazon, but not the i4. What's the difference in the new version?
Here's a link: NEW i4 | Nitecore. Looks like they have changed the charge rate on the bays. But, I've seen some discrepancies between listings. One says 0.5A on 2 bays, another says it's 0.5A on all four. Guess I'll have to wait and see, or just buy one when they get released.
I would not recomend any Charger that has an internal transformator and is not using a Power supply. The most problematic part in a charger in terms of safety is the part in which 110V are reduced to 12V, or 5V (in Europe 220V).
I'm sold on xtar's 3-stage charging.... almost scorched my brand new HG2's in two different Nitecore i4's. My VC4's and VC2 Plus stay cool to the touch at all times. I gave away both Nitecore i4's.

I am not electric-Ing., but as far as I know Li-Ion charging method is CC-CV. The TC that xtar mention is relevant, when a battery is slightly deep discharged. The charger detect the voltage in the battery and Charge with lower current, till the battery reaches a certain Level of Voltage.
Almost all new microprocessor controlled Chargers nowadays are doing that.
Almost all new microprocessor controlled Chargers nowadays are doing that.
Li-on chargers supply a constant current, detect ascending voltage, and maintain voltage at a preset max level until the current reaches a set cutoff point.
It's the same way that cell phone chargers work to charge flat pack lithium cells.
I bought the Nitecore Intellicharger New i4 and i send an email to Nitecore for more specifications so here what they send me:
Thanks so much for your support of NITECORE's products.
For New I4 charger, firstly, I want to let you know that the slot 1&3 are use same circuit, and slot 2&4 are use same circuit.
1. Only one battery, no matter which slot, it all would charged at 1.5A automatically.
2. For two batteries, no matter which two slots, they all would charged at 0.75A automatically.
3. For three batteries, use slot 1&2&3, the battery in the second slot will be charged at 0.75A, whilst the other
two batteries will be charged at 0.375A each (because slot 1 and slot 3 are use the same circuit, the charging current would be average at 0.75A/2=0.375A). On the contrary, if use slot 2&3&4, the battery in the third slot will be charged at 0.75A, whilst the other two batteries will be charged at 0.375A each (because slot 2 and slot 4 are use the same circuit, the charging current would be average at 0.75A/2=0.375A).
4. For four batteries, all would charged at 0.375A.
During the charging process, the first LED would blink firstly, after a while, the first one would become solid and the second LED would blink. If all three LEDs become solid. it means the battery has been fully-charged.
PS: All batteries would be charged together at different charging current.
Hope this would help you.
Thanks,
